Need everyones opinion on why the radiator is smoking.

Priority #1,Get rid of the exhaust outside

Two words IR and gun, that's IR-Gun
If the rad is painted, it will smoke for a while, but not an hour.
Do a pressure test, to 15 psi.If it passes,Wash the rad with clear water as suggested.
If you are concerned about overheating: remove the stat and install a restrictor, then run it up again, keeping tabs on things with the........ IR-Gun..
The rad should knock the water temperature down to about 85/90% or so between the top and bottom of the rad, With good airflow through the rad. That means with a 195 stat, the temp should drop to about 175/165. With a 160 stat, it might drop to 145/135. If you are running this beast in an enclosed space with the air temperature continually rising, and the carb sucking up hot air as well,or if you are missing a shroud,then you may not get a proper temperature drop.
With the stat removed, the temp might not come up very well, or it will take a long time.
If the engine shakes that bad, try putting some advance into it. Just yank the dizzy to where it runs smoothest. Then begin the tune.Start with the T-port sync.
